wifi: rtw89: phy: disable CFO track when two PHY are working simultaneously

Browse Source 
To have good performance, adjust hardware XTAL to track CFO (carrier
frequency offset). However, there is only one hardware XTAL, so it is not
possible to track on two PHY simultaneously. It also can't track on single
one PHY when two PHY are working, because the adjustment of XTAL will
affect all PHY. Thus, disable CFO track for this case.
